基于71个性状的193个形态特征状态，对35个哺乳动物类群进行了系统发育分析，以检验几种关于脂虫关系的假说，包括Lipotyphla、Tenresidae、马达加斯加Lipotyphlan和加勒比海Lipotyphla。除了哺乳动物的系统发育之外，对这些假设的明确测试对于理解有关马达加斯加和加勒比海生物地理学的更大问题也是至关重要的。在方法上，创建了几个不同的参数，用这些参数来确定所得到的分支对关于后验字符加权、缺失数据和多状态字符排序的初始假设的敏感性。这一数据集产生的分支，尽管这些参数有扰动，但仍然出现，并得到其他置信度评估技术的支持，这与马达加斯加天牛单系和山梨科与加勒比海分类群Solenodon的联系相矛盾。关于TenreCid和Lipotyphlan单调的结果更加模棱两可，并且依赖于关于字符排序、加权和缺失数据的处理的某些假设。支持非洲哺乳动物分支的另一种系统发育没有得到这里讨论的数据集的支持。(C)1999年威利·亨尼格协会。
A phylogenetic analysis of 35 mammalian taxa focusing on the lipotyphlan family Tenrecidae, based on 193 morphological character states across 71 characters, is undertaken to test several hypotheses of lipotyphlan relationships, including monophyly of the Lipotyphla, Tenrecidae, Malagasy Tenrecidae, and Caribbean Lipotyphla. Explicit tests of these hypotheses are central to understanding larger issues concerning Malagasy and Caribbean biogeography, in addition to mammalian phylogeny. Methodologically, several different parameters are created with which to determine the sensitivity of resulting clades to initial assumptions about a posteriori character weighting, missing data, and multistate character ordering. Clades produced by this data set that appear despite perturbations in these parameters and that are supported by other confidence-assessment techniques contradict Malagasy tenrecid monophyly and the association of soricids with the Caribbean taxon Solenodon. Results regarding tenrecid and lipotyphlan monophyly are more ambiguous and depend on certain assumptions regarding treatment of character ordering, weighting, and missing data. An alternative phylogeny supporting an African mammal clade receives no support from the data set discussed herein. (C) 1999 The Willi Hennig Society.
